Title: Science Citation Knowledge Extractor


Invention: The Science Citation Knowledge Extractor (SCKE) uses natural language processing as well as machine learning to analyze biomedical research databases and extract key concepts from papers that are citing certain research. The Latent Semantic Analysis and Latent Dirichlet Allocation algorithms are used to do so, allowing researchers to see how the scientific community is using their research.


Background: Not only are researchers interested in published scientific literature, they also want to know how their publications are being used in the broader scientific community. This software meets this need by using natural language processing to extract topics out of texts that cite a researcher’s publication.
